Disk

Use the Disk statement to specify a virtual address or a directory ID to be used by the Tape Manager Machine (TMM). It is recommended that the specified addresses be used if a directory name is not specified. A directory ID may be used, rather than a minidisk (MDISK) virtual address, for DB1, DB2, DB1BKUP, and DB2BKUP. On a request node, only the TCPIP disk is valid.

Delete or comment out the DISK TCPIP statement unless you specified a host name in either the Define_Local_Node or Define_Remote_Node statements.

The DISK TCPIP statement specifies the virtual address of a CMS disk that may contain files that are required for host name resolution. The TCPIP DATA file on the disk may contain the NSINTERADDR statement that specifies the IP address of the name server(s). The TCPIP DATA is likely to be found on the TCPMAINT 592 disk.

If the DISK TCPIP statement is needed, it is recommended that a link to the disk be placed in the directory entry of the TMM user ID.

Several parameters can be used to specify a virtual address or directory ID. These parameters are described below.

DB1
Contains the detail information for tapes and tape pools.
DB2
Contains the tape pool volume files.
DB1BACKUP
Specifies the Migration Tool backup disk for DB1 that can also be used for real-time backups.
DB2BACKUP
Specifies the Migration Tool backup disk for DB2 that can also be used for real-time backups.
TCPIP
Specifies the virtual address of a CMS disk that contains files that might be required for host name resolution. The TCPIP DATA file may contain the NSINTERADDR statement that specifies the IP address of the name server(s). The TCPIP DATA is likely to be found on the TCPMAINT 592 disk. If the TCPIP disk statement is needed, it is recommended that a link to the disk be included in the directory entry of the TMM user ID.
USER
Specifies the virtual address for TxTMM to use to link to and access a user disk when the FILE parameter is specified on a command, such as TAPEADD.
Note: In a Shared Catalog environment:
  • The DB1, DB2, DB1BACKUP, and DB2BACKUP statements should be specified only on the catalog node.
  • Only the TCPIP and USER disk statements are valid for a request node.

Example:

/*       Name  Vaddr or Directory Name        */
/*       ----  -----------------------------  */
/* DISK  DB1   0200                           */
/* DISK  DB2   0210                           */
/* DISK  DB1   VMDEVU:VMABCLIB.EUM.TXTMM.200  */
/* DISK  DB2   VMDEVU:VMXYZLIB.EUM.TXTMM.210  */

Disk DB1 		0200
Disk DB2 		0210
Disk DB1BKUP 1200
Disk DB2BKUP 1210
Disk USER		0C91
Disk TCPIP		0592
